Abstract (en)

An organic light-emitting device is provided comprising a stack of layers including - an electro-optical layer structure (10) having a light emissive surface (12), - a light extraction structure (20) adjacent the light emissive surface, the light extraction structure has a nanostructured layer (22); and a backfill layer (24) comprising a material having a second index of refraction different from the first index of refraction, wherein the backfill layer (24) forms a planarizing layer over the nanostructured layer (22). The light emitting device includes a barrier film that comprises a first and a second inorganic layer (22, 26) and an organic layer (24) arranged between said inorganic layers. The one (22) of the inorganic layers of the barrier film closest to the electro-optical layer structure forms the nanostructured layer and the organic layer (24) between the inorganic layers forms the backfill layer.
